Servlet doesn't want to compile

[Tammer Salem]

Hi,
I'm having problems compiling my servlets.
I have a servlet called (HelloWorld.java) in a directory (D:\Program Files\Apache 
Tomcat 4.0\webapps\test\WEB-INF\classes). My javac.exe is in (D:\j2sdk1.4.1_01\bin). I 
can't get the servlet file to compile. I think my CLASSPATH and Path environment 
variables are messed up, because I keep on getting the following exceptions:

=================================
HelloWorld.java:2: package javax.servlet does not exist
import javax.servlet.*;
^
HelloWorld.java:3: package javax.servlet.http does not exist
import javax.servlet.http.*;
^
HelloWorld.java:11: cannot resolve symbol
symbol  : class HttpServlet
location: class HelloWorld
public class HelloWorld extends HttpServlet
                                ^
HelloWorld.java:13: cannot resolve symbol
symbol  : class HttpServletRequest
location: class HelloWorld
        public void doGet(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException

                          ^
HelloWorld.java:13: cannot resolve symbol
symbol  : class HttpServletResponse
location: class HelloWorld
        public void doGet(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException

                                                      ^
HelloWorld.java:13: cannot resolve symbol
symbol  : class ServletException
location: class HelloWorld
        public void doGet(HttpServletRequest request, HttpServletResponse response) 
throws ServletException, IOException

                                                                                       
    ^
6 errors
=================================


and here is the code:
=================================
import java.io.*; 
import javax.servlet.*;
import javax.servlet.http.*;

public class HelloWorld extends HttpServlet 
{
 public void doGet(HttpServletRequest request, HttpServletResponse response) throws 
ServletException, IOException
 {
  PrintWriter out = response.getWriter();
  out.println("Hello World");
 }
}
==================================

I can compile regular Java files with no problems. Only when I import any javax. 
packages do I get errors.
Can anyone please help me?


thanks,
